Quick review \u2014 3 minutes\n\nReview these four hazard categories with students.\n\nHow to Do Ergonomics in Construction - Work-Fit\n\n### 1. Falls\n\nCommon causes: unprotected edges, floor openings, unsafe ladders, and scaffolds.\n\nPrevention: Use required fall protection, guardrails, secured covers, and properly inspected ladders and scaffolds.\n\n25 Pedestrian Detection Systems \u2014 2026 Directory\n\n### 2. Struck-by\n\nCommon causes: moving vehicles, falling tools or materials, and flying debris.\n\nPrevention: Wear high-visibility clothing, stay clear of equipment travel paths, secure materials, and use required eye and head protection.\n\nTrench Box Installations Require Knowledge of OSHA Safety Rules : CEG\n\n### 3. Caught-in/between\n\nCommon causes: trench collapses, unguarded machinery, and workers caught between equipment and fixed objects.\n\nPrevention: Use required trench protection, keep machine guards in place, and stay clear of pinch points and swing radii.\n\nElectrical Safety PPE Checklist for 2025: Gloves, Mats, and Arc Flash\n\n### 4. Electrocution\n\nCommon causes: damaged cords, exposed energized parts, overhead power lines, and improper grounding.\n\nPrevention: Inspect cords and tools, use required ground-fault circuit interrupter (GFCI) protection, maintain safe distances from power lines, and have qualified personnel control electrical hazards.\n\n## 2. Eight review questions \u2014 5 minutes\n\nHave students answer independently or with a partner. Allow about 30\u201340 seconds per question.\n\nChoose one answer per question.\n\n0/8 answered\n\n1. A worker is installing roof sheathing near an unprotected edge. Which Focus Four hazard is the primary concern?\n\nA. Struck-by\n\nB. Falls\n\nC. Electrocution\n\nD. Caught-in/between\n\n2. A forklift backs up while a worker walks behind it. What hazard is present?\n\nA. Falls\n\nB. Electrocution\n\nC. Struck-by\n\nD. Caught-in/between\n\n3. A trench wall collapses and traps a worker. Which hazard category applies?\n\nA. Caught-in/between\n\nB. Struck-by only\n\nC. Falls only\n\nD. Electrocution\n\n4. A worker uses a power tool with a damaged electrical cord. What is the safest action?\n\nA. Wrap it with tape and keep working\n\nB. Use it only for a short task\n\nC. Remove it from service and report it\n\nD. Ask another student to hold the cord\n\n5. Which action helps prevent a struck-by injury from falling tools?\n\nA. Leaving tools on a scaffold edge\n\nB. Securing tools and keeping people clear of the area below\n\nC. Wearing gloves only\n\nD. Working faster\n\n6. Before using a ladder, what should a worker do?\n\nA. Check its condition and set it up properly\n\nB. Stand on the top cap of any ladder\n\nC. Place it on loose debris\n\nD. Lean it against an unstable surface\n\n7. A worker reaches into an operating machine to clear a jam. What should happen first?\n\nA. Reach in quickly\n\nB. Ask a coworker to watch\n\nC. Stop and follow the proper energy-control procedure\n\nD. Wear thicker gloves and continue\n\n8. Which is an important way to reduce electrical shock risk on a construction site?\n\nA. Use damaged extension cords if they still work\n\nB. Ignore overhead power lines if wearing a hard hat\n\nC. Use required GFCI protection and inspect electrical equipment\n\nD. Handle electrical repairs without training\n\n Check answers\n\n## 3. Quick group scenario \u2014 5 minutes\n\n236117: New Housing For-Sale Builders & Home Construction | item.com\n\n## Scenario: A busy construction site\n\nYour crew is preparing a house addition. You notice the following:\n\n- A worker is standing near an unprotected second-floor edge.\n- An excavator is backing up near a worker on foot.\n- A trench has unsupported sides where soil could collapse.\n- An extension cord has exposed wiring near a damp area.\n\nGroup task: In teams of 2\u20134, identify the hazard category for each problem, explain what could happen, and propose a safe corrective action.\n\nTime: 3 minutes to discuss, 2 minutes to share answers.\n\n### Instructor answer key\n\n| Hazard observed | Focus Four category | Safe response |\n| --- | --- | --- |\n| Unprotected second-floor edge | Falls | Stop unsafe work and provide the required fall-protection system. |\n| Excavator backing near a pedestrian | Struck-by | Keep pedestrians out of the equipment's path and follow site traffic-control procedures. |\n| Unsupported trench sides | Caught-in/between | Keep workers out of the hazardous excavation until the required protective system is in place and the excavation is inspected by a competent person. |\n| Exposed wiring near damp ground | Electrocution | Do not touch or use the cord; keep people clear and have it removed from service by appropriate personnel. |\n\nDiscussion follow-up: Which hazard would you address first, and why? Students should recognize that all four conditions need prompt attention. Workers should stop or avoid unsafe work and notify the supervisor; the immediate response depends on the severity and circumstances.\n\n## 4. Exit ticket \u2014 2 minutes\n\nAsk students to answer these verbally or on a scrap of paper:\n\n- Name all four Focus Four hazards without looking at your notes.\n- Give one prevention method for each hazard.\n- What should you do if you discover a serious hazard on the jobsite?\n\nSuccess criteria: Students can name all four categories and identify at least one appropriate preventive action for each.\n\nInstructor note: This is a supplemental review activity, not a substitute for OSHA-authorized training or the required OSHA 10-Hour Construction course. For formal instruction, verify specific requirements against current OSHA construction standards and your authorized trainer's materials.\n\n[item.com](<https://www.item.com/naics/236117>)", "capture_note": "the 8 questions came as a clickable quiz; answers were not shown in the copied text"}
